The only item that makes the amount of noise it does, that you can legally; sell, or use, without a silencer. is a gun.
In 1884 Hiram Maxim invents the machine gun, very quickly losing his hearing. Around 1902 his son Hiram Percy Maxim invents and starts selling the first commercially successful firearm silencer, receiving a patent on March 30, 1909. A hundred and something years later they still work in the same way. A series of baffles slow the flow of the rapidly expanding gasses. Despite many different advances in baffle design. Volume is still the name of the game, the bigger the space available to contain the gases, the greater the effect.

If you ever wondered about the intelligence and foresight of your elected representatives, the silencer is the perfect proof of what you should have suspected all along. Even the most dazzling intellects amongst them are quite happy to spend your money, acting against your interest, based on what they saw on TV or at the movies. Let's take where I live as an example. 20 years ago Police forces, ever fond of inventing powers they haven't been given by government, were extremely resistant to issuing licences for sound moderators. Until the Forestry Commission's legal department realised gunshots in the workplace were endangering the hearing of their deer managers and asked who was accepting liability. In Northern Europe they're a safety feature, with demands to legislate their use as protection for your dog's hearing. In Southern Europe the tool of an assassin, with no legitimate use.
Over the last ten years moderators/silencers/suppressors have followed the exact opposite trajectory to your pal SBW, getting lighter, and quieter. I've owned a few. So far the choice has been: very heavy and durable, or pretty light and basically disposable. Sealed, or strippable, out front, or both out front and behind the muzzle. Steel, titanium, or aluminium baffles in a tube of the same materials or even carbon fibre. All have their fans. The heavy ones are great for the range. the stalking designs get lighter.Just like bipods, something that was once quite crude and inexpensive can now be the cost of a new rifle. Yep both have crossed the $/£/E 1,000 price point. Yikes.

A few years ago there appeared a new technology, but at three to four times the price its adoption hasn't been that widespread. I was keen to find out more. Bert Wilson, owner of Oceania Defence in NZ patented a process for 3D printing moderators and partnered with Ram3D. At 190g they are much lighter than anything we've seen before. His UK sales team sold a few to the NRA(uk) who unfortunately for them, and fortunately for me, blew one up. When the rest hit the auction, James at Jagersporting was quick off the mark snapping them up. He sold them off to his customers at a massive discount on the list price.
I spoke to the NRA armourer who told me he knew two people who were using Oceania Defence moderators for deerstalking and I should be totally unconcerned. The current advice is clean in an ultrasonic every 500 rounds.
My totally subjective and unscientific opinion. They are amazing! 190g feels like nothing! Those big steel mods of a few years ago are like banging rocks together while OD have rocked up in a space shuttle.
Last time I looked list was £680 + another £100 for the titanium adapter. pretty chronic if you have to have more than one, almost bearable if you're swapping it between several rifles. [Word to the wise never ever use a mod that's been on a rimfire even for one shot on a centre fire, unburned powder init]

The one thing I'd do differently is the 'out front' designs can't overcome the fact that the over barrel designs have more volume and anything that moves the balance of a stalking rifle to the mag well is a good thing . There's already another 3D printed over-barrel design by Roedale in Germany but it's 1100+ euro and almost double the weight. Double yikes! For readers in the USofA the comparison seems to be the Banish 30 Gold-V2 which Silencer Central have for $1300. also about double the weight
Considering the weight penalty and price hike I'd still go for the Oceania Defence.
More soon
